Ready for another Teen Momshocker? Of course you are ... or at least you expect to be shocked by these kids these days, don't you? Jenelle Evans is one of the best at making our jaws drop, but this time it's her on-again/off-again boyfriend KiefferDelp who has left us floored.

Did you know Jenelle isn't the only teen parent in that relationship? Turns out ol' Reefer has a child of his own. A son to be exact.

Jenelle dropped that little tidbit on -- where else? -- Twitter this week, after someone criticized her parenting skills (or lack thereof). When someone mentioned the fact that Kieffer has a relationship with his mom, and his mom -- unlike Jenelle's -- hasn't had to take custody of his child, the Teen Mom star suggested people ask Kieffer about his own child. Kieffer's response was at once a confirmation that it's true and a warning that she needed to stop talking. All he would say?

Well, good for him! At least his parents did one thing right in raising this kid! Then again ... do we really want to be slapping Kieffer's parents on the back?

Once upon a time it was normal for teen parents to have kids and then move on, to pretend like it never happened. Especially teen boys.

But this is 2012. If Kieffer has a child -- and it certainly sounds like he does -- that child needs to be a priority in his life. And as much as we don't like to admit it, teen parents still need parental guidance. That's why teen parenting is such a problem in the first place ... they're still just kids.

We don't know much about his dad, but Kieffer's mom is currently embroiled in a Jenelle sex tape scandal. And she's raised a child who has no problem sharing his affection for weed with the world, but never once mentioned that he has an actual child. Not to mention Kieffer has been arrested how many times now?

Now we add in the fact that her teenage son was dating a girl and hanging out with her child while his own son was where exactly? This sounds like another colossal parenting failure from the Teen Mom crew ... doesn't it?
